RALPH S. JENNINGS, OF BALTIMORE, MARYLAND.

SUPPORTER FOR LEATHER- BOARD.

SPEGIFIQATION forming part of Letters Patent No. 268,494, dated December 5, 1882.

Application filed September 25, 1882. (No model.)

To all whom it may concern Be it known that I, RALPH S. JENNINGS, of the city and county of Baltimore, of the State of Maryland, have invented a new and useful Improvement in Supporters for Leather-Board while in the Process of being Dried; and Ido hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure l is a side elevation, Fig. 2 a transverse section, Fig. 3 an edge View, and Fig. 4 a longitudinal section, of a supporter containing my invention, the nature of which is de-' Thick card-board, usuallytermed in trade leatherboard, in the process of drying is very apt to become warped, so as to render it difficult to calender it or otherwise treat it in finishing it for use.

My invention or improved supporter is to firmly hold the leather-board while being dried, so as to prevent it from warping.

In the drawings, A and B represent two rectangular frames, each being made like an ordinary window-blind, except in having each of the slats a of it'to stand at right angles with, instead of obliquely or at acute angles to the planeof its sustaining-frame b. In each of such frames are two series of slats, with a divisional bar, 0, between them, and arranged in the middle of the frame. The two slatted frames A B are of like size, and connected at one edge of each by hinges, as shown at 61, such frames at their-opposite edges being furnished with hooks e and eyesffor holding them together. Besides such, there are to each of the two longer bars of one of such frames two hooks, g g or it h, each book of the upper pairof hooks standing in a plane whichif produced would be at right angles to the plane of the hook it, immediately below such hook g, such being to enable each of the cardboard supporters to be readilyhooked to another, in

order fora series of them to be hooked together and depend from a common support.

When the frames A and B are closed together, there is to be a space between them equal or about equal in thickness to that of a sheet of the leather-board to go between them. After a supporter, as described, may have been suitably charged with sheets of leather-board in a wet or moist condition, the t'rarnesare to be closed upon them and hooked together and set up or suspended in a suitable drying atmosphere or room, and with suitable spaces between the supporters for air to freely circulate between them and in contact with the sheets ofleather-board. By the slats and crossbars of the two frames of each supporter the sheets ofleather-bonrd will be firmly sustained and prevented from warping (luring theprocess of desiccating them.

I do not claim a card-board supporter consisting of two rectangular frames hinged togcther and provided with lacings arranged in them in manner as shown in the United States Patent No. 31,822. Nor do I claim :a strawboard supporter consisting of two rectangular frames hinged together and having open sides consisting of lattice-work, wirc-gauze, or bars, as shown in the United States Patent No. 59,806.

I claim as my invention-- Theleather or cardboard supporter, substantially as described,consistingot' the two slatted frames A B, hinged to each other and provided with books and eyes or other proper means of closing them together, and also with books applied to one of them and projecting from its opposite bars, and arranged substantially as described.

RALPH S. JENNINGS.
